Temperatures climbed into the low to mid-90s in the afternoon, and it will feel like between 105-109 degrees, ABC7 Chicago AccuWeather Meteorologist Mark McGinnis said. But the heat is not stopping from coming to enjoy Monday night's Summer Series concert at Millennium Park.

Monday’s heat advisory is set to expire at 8 p.m. The advisory cautioned heat index values of up to 109 degrees.

The National Weather Service has issued a heat advisory for the entire Chicago area ahead of more hot and humid conditions.
